Answer:

Step-by-step explanation:

(x+4) ^ 1/3 = 7

We need to cube each side of the equation

(x+4) ^ 1/3 ^3= 7^3

x+4 = 343

Subtract 4 from each side

x+4-4 = 343-4

x = 339

The power raised on each side is 3

Answer:

assuming this is a rectangle:

VW=31

WX=19

YW=36.36

ZX=18.18

VX=36.36

Step-by-step explanation:

VW=VX

VW=31

WX=VX

WX=19

YW^2=19^2+31^2

YW^2=361+961

YW^2=1322

YW=36.36

ZX=1/2VX

ZX=18.18

VX=YW

VX=36.36

Find all complex solutions of 7x^2-7x+3=0

Sedaia [141]

Answer:

The complex solutions are

$x = (\frac{7-\sqrt{35} i }{42} , ) x = \frac{7 + \sqrt{35} i }{42})$

Step-by-step explanation:

Step(i):-

Given equation 7 x² - 7 x +3=0

$x = (\frac{-b -\sqrt{b^{2}-4ac } }{2ac} , \frac{-b +\sqrt{b^{2}-4ac } }{2ac})$

Given standard equation

a x² +b x +c =0

a = 7 , b= -7 and c=3

Step(ii):-

$x = (\frac{-(-7) -\sqrt{(-7)^{2}-4(7)(3) } }{2(7)(3)} , \frac{-(-7) +\sqrt{(-7)^{2}-4(7)(3) } }{2(7)(3)})$

$x = (\frac{7-\sqrt{(49-84 } }{42} , \frac{7 +\sqrt{(49-84 } }{42})$

$x = (\frac{7-\sqrt{35i^{2} } }{42} , \frac{7 + \sqrt{35i^{2} } }{42})$

$x = (\frac{7-\sqrt{35} i }{42} , \frac{7 + \sqrt{35} i }{42})$

Solve the inequaility - x/4 <2

IrinaK [193]

❄ Hi there,

let us start by considering this: What should we do to get x all by itself?

Since it's

divided by 4
multiplied by -1

we should

multiply (both sides) by 4
divide (both sides) by -1

So, let's start.

$\sf{\dfrac{-x}{4}\times4 < 2\times4}}$

$\sf{-x < -8}$

$\sf{x > 8}$

When we divide both sides of an inequality by a negative number, we do "the inequality flip" and flip the inequality sign.
